For cancer in the antrum and lower stomach — what the robot changes in the way the operation is done, and what it leaves exactly as it was. Apollo Hospital, Bhat, Gandhinagar · Gota OPD, Ahmedabad.
Last updated: 3 October 2026
Shah’s Gastro, Cancer & Robotic Surgery Centre. Dr Harsh Shah trained in surgical gastroenterology as a super-specialty and holds two higher qualifications in it. Lower-stomach cancers are planned at the tumour board, and the robotic, keyhole or open route for each distal gastrectomy is chosen there, case by case.
A robotic distal gastrectomy removes the same lower part of the stomach, with the same lymph node field, as an open or keyhole operation. The robot does not change what is taken out; it changes how precisely the hardest part is done.
The hardest part is the clearance of lymph nodes along the arteries that run over the pancreas. Wristed instruments and a steady, magnified view let the surgeon lift the nodes off the pancreas instead of pressing on it.
Robotic and keyhole patients recover on the same early-feeding pathway. The robot takes longer in theatre and costs more, so it earns its place where the dissection is demanding, not in every case.
The operation itself does not change. The lower part of the stomach is removed with its fatty apron and two tiers of lymph nodes, a clear margin of normal stomach is left above the tumour, and food passage is rebuilt. What the robot changes is the way the surgeon’s hands reach the tissue.
In laparoscopic surgery the instruments are rigid sticks that pivot at the abdominal wall, and the camera is held by an assistant. In robotic surgery the surgeon sits at a console a few feet from the patient, looks into a three-dimensional magnified view that he controls himself, and moves instruments that bend at a wrist inside the abdomen.
Three things follow from that, and only three are worth a patient’s attention. The instrument tip can approach a vessel or a lymph node from an angle a straight instrument cannot reach. The view is steady, because no tired hand is holding it. And a third robotic arm can hold tissue still in one position for as long as it is needed, so the surgeon is not depending on a second person to keep the field open.
Dr Harsh Shah’s position is narrow and deliberate: the robot is a means to a complete operation, never a reason to do a smaller one. A robotic distal gastrectomy that clears fewer nodes is not a gentler operation, it is a lesser one.
A distal gastrectomy suits a cancer in the antrum — the outlet end of the stomach — or in the lower body, where a safe margin of normal stomach can be left above the growth. When that margin cannot be achieved, the operation becomes a total gastrectomy, whichever approach is used.
This page assumes the diagnostic work is complete: the endoscopy and biopsy, the staging CT, the staging laparoscopy where it was needed, and the tumour board’s plan. The order of treatment — operation first, or chemotherapy first and the operation four to six weeks after the last cycle — is settled there and is explained on the robotic stomach cancer surgery page. What follows is about the operation itself.
A growth reaching towards the middle of the stomach, or a diffuse-type cancer that spreads inside the wall beyond what the endoscope sees, may need the whole stomach. Where there is doubt at the upper edge, the margin goes for frozen section while the patient is asleep, and the resection is extended if the report says so.
The patient lies on the back with the head of the table raised, so the bowel falls away from the stomach. Small ports are placed in an arc across the upper abdomen, the robotic arms are docked to them, and the surgeon moves to the console. A separate port lets the bedside assistant pass staplers and clips.
The set-up is planned rather than improvised, because port positions decide what the instruments can reach later in the operation. Four robotic ports sit in a gentle curve across the upper abdomen, wide enough apart that the arms do not collide. A larger assistant port, usually on the right, carries the stapler. The left lobe of the liver is lifted out of the way with a retractor through a small opening under the breastbone, because the lesser curve of the stomach and the arteries beside it lie directly beneath it.
Positioning, padding and warming are completed before docking, because the patient cannot be moved afterwards. If anything requires the abdomen to be opened, the arms are undocked and the operation continues open — a decision of judgement, never a failure of the method.
At the end the stomach specimen, with its lymph node fan attached, is placed in a bag and lifted out through one short incision, sized to the specimen and placed where it heals with least pain.
A distal gastrectomy with D2 dissection has four phases. The robot’s advantage is greatest in the third, the clearance of nodes along the arteries over the pancreas, which is the most demanding part of the operation in any approach.
Phase one — the fatty apron and the left side. The omentum is lifted off the colon and the lesser sac is entered. On the left the blood vessels running to the greater curve are divided, but the main supply to the part of the stomach that will stay is preserved, because that remnant has to live on what is left.
Phase two — below and above the pylorus. Below the outlet of the stomach the vein that drains the greater curve joins a short trunk of veins in front of the pancreas. The rule there is to divide the stomach’s own vein exactly where it joins, and never the trunk itself; a magnified, steady view makes that precise. The duodenum is then divided just beyond the pylorus and its end is buried with stitches, because the duodenal stump is one of the two places where a leak can begin.
Phase three — the nodes over the pancreas. The nodes along the common hepatic artery, around the coeliac trunk, along the left gastric artery and the first part of the splenic artery sit on and just above the pancreas. With rigid instruments this tissue is often reached by pushing the pancreas down. Pressing on pancreatic tissue is what causes a pancreatic leak after gastric surgery. With wristed instruments the surgeon can lift the packet of nodes up and peel it off the pancreatic surface instead, sealing small vessels with fine bipolar energy close to the gland without spreading heat into it.
Phase four — division and reconstruction. The stomach is divided with a stapler at the chosen level, the margin checked, and food passage restored. The default reconstruction is a Roux-en-Y gastrojejunostomy, which carries bile and pancreatic juice in well downstream of the new join and protects the remnant from bile reflux. A Billroth I join to the duodenum is used selectively when a generous remnant allows it without tension. Every join is tested for leaks before closure.
All three approaches remove the same stomach and the same nodes, and the long-term cancer results of keyhole distal gastrectomy have matched open surgery in large trials. The differences are in the incision, the recovery and the precision of the hardest dissection — and in cost.
| Open | Keyhole (laparoscopic) | Robotic | |
|---|---|---|---|
| Incision | A long upper-abdominal cut | Five small ports and one short extraction cut | Five small ports and one short extraction cut |
| What the surgeon sees | Naked eye, light from above | Magnified 2D or 3D screen, camera held by an assistant | Magnified 3D view controlled by the surgeon |
| Instrument movement | Hands and straight instruments | Rigid instruments that pivot at the wall | Wristed instruments that bend inside the abdomen |
| Blood loss | Highest of the three | Low | Low, similar to keyhole |
| Node clearance | D2 standard | D2 standard | D2 standard; the wrist helps most along the arteries over the pancreas |
| Time in theatre | Shortest | Longer | Longest |
| Hospital stay | Longest | Shorter | Similar to keyhole |
| Return to ordinary activity | Slowest, limited by the wound | Sooner | Similar to keyhole |
| Cost | Lowest | Moderate | Highest — the main drawback |
| Where it fits | Bulky tumour through the outer wall, many previous operations | Most early and many locally advanced distal cancers | Demanding dissection above the pancreas, a heavier patient, a narrow working space |
Read the table in both directions. For a small, early cancer of the lower stomach in a slim patient, keyhole surgery already does this operation well, and the extra cost of the robot buys comparatively little. The advantage of the robot grows with the difficulty of the dissection — a heavier patient, a deeper node field, tissue stiffened by chemotherapy — and that is where Dr Harsh Shah reserves it.
Blood loss in a robotic distal gastrectomy is usually small, the pathologist counts every lymph node removed, the hospital stay follows a written recovery pathway rather than a fixed number of days, and the return to work is set at the two-week review.
Blood loss. Bleeding is controlled vessel by vessel under magnification, and a transfusion is not part of the plan. It remains possible, and it is named among the risks before consent.
Lymph nodes. The specimen leaves theatre with the node stations labelled. The pathology report states how many nodes were examined and how many contained cancer. With the depth of the tumour, that count decides whether chemotherapy is advised afterwards.
The stay. Recovery runs on an enhanced-recovery pathway. You sit out of bed on the evening of surgery and take sips of water; on the first day you walk, take liquids and the urinary catheter comes out; over the next two or three days a soft diet is built up and drips are stopped. A nasogastric tube is not routinely left after a distal gastrectomy, and a drain is not routine either. You go home when you meet the criteria — no fever for a full day, eating a soft diet, walking without help, comfortable on tablets — not when a date arrives.
Work. Small incisions rarely limit you for long; what sets the pace is learning to eat with a smaller stomach. Desk work usually returns before physical work, and the timing is agreed at the two-week visit.
A robotic approach is not offered where it would compromise the cancer operation. A tumour that has grown through the outer wall of the stomach, a tumour stuck to a neighbouring organ, or an abdomen scarred by several previous operations is usually better served open.
Long-term follow-up of the keyhole distal gastrectomy trials has raised one specific caution: when the tumour breaches the outer layer of the stomach, an open operation gives the surgeon more freedom to clear the surface and the surrounding tissue completely. That caution applies to the robot as much as to keyhole surgery. A bulky tumour after chemotherapy, a growth adherent to the pancreas or colon, or a planned removal of more than one organ is assessed on its anatomy, and open surgery is frequently the correct choice rather than a fallback.
Fitness matters too. A robotic gastrectomy means a longer anaesthetic with the abdomen inflated with gas; for a few patients with severe heart or lung disease the shorter open operation is safer, a judgement made with the anaesthetist well before surgery.
Finally, the robot does not replace the staging decision. If disease is found on the lining of the abdomen at staging laparoscopy, a radical gastrectomy by any route is not the right operation, and the plan changes at the tumour board.
Because part of the stomach remains, eating after a distal gastrectomy is closer to normal than after a total gastrectomy. Meals are smaller and more frequent at first, fluids are taken between meals rather than with them, and most people settle into a comfortable pattern within a few months.
Two problems are planned for rather than waited for. Dumping — light-headedness, sweating or cramps soon after eating — improves with smaller portions, less sugar and drinks taken apart from solids. Bile reflux, a burning discomfort from bile washing back into the remnant, is what the Roux-en-Y arrangement is designed to prevent.
Vitamin B12 and iron are watched and replaced on a schedule for life, because the stomach’s role in absorbing them is reduced. A dietitian is part of the pathway from the two-week visit onwards, not an extra for those who struggle.

A robotic gastrectomy costs more than a keyhole or open operation, mainly because of the robotic instruments used for each case and the longer theatre time. The office prepares a written estimate before admission, so you compare a document rather than a conversation.
What moves the estimate is the length of stay, the room category, whether chemotherapy is part of the plan, intensive care if it is needed, and the approach itself.
Cashless admission is arranged at Apollo Hospital, Bhat where your policy allows it, and the pre-authorisation paperwork is prepared by the office. Ask specifically whether your policy covers robotic surgery and at what limit — policies differ on this more than on any other point. Bring your policy documents, photo identity, all reports and a list of current medicines to the admission.
No. The robot has no independence of its own. Every movement of every instrument is made by Dr Harsh Shah's hands at the console, scaled and steadied by the system. A bedside surgical team stays with the patient throughout.
No. The extent of the operation is set by the tumour — its position, its type and the margin it needs — and is the same whichever approach is used. The robot changes how precisely the dissection is done, not how much is removed.
Not automatically. Both give the same cancer operation with small incisions. The robot's advantage is greatest where the node dissection over the pancreas is demanding — a heavier patient, a deeper field, tissue stiffened by chemotherapy. For a small early cancer in a slim patient, keyhole surgery is an equally good choice at lower cost.
The robotic arms are undocked and the operation continues open, with the same steps and the same standard. This is a judgement made in your interest during surgery, and it is discussed and consented for in advance.
The aim is a complete D2 field, and the pathology report states exactly how many nodes were examined and how many contained cancer. Ask for that number at the two-week visit; it is part of how the need for further treatment is decided.
